Use the Matrix as a soft, broad fill light with the Pop-Up Softbox. This custom designed accessory features built-in rod mounts that allows the softbox to attach directly to the light head with no speed ring required. The level of diffusion is adjustable with included inner and outer baffles, and the optional grid accessory takes the light-shaping abilities of the softbox even further. Each Matrix Softbox comes with a travel bag and is collapsible for easy transport.
